- JOHN F. AMES, or PORTLAND, OREGON. MOLD FOR DEPOSITING PRINTING-ROLLER COMPOSITION ON FABRICS.

No. 816,144. Y

Be it known that 1, JOHN F. AMEs, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Molds for Depositing'Printing-Roller Composition on'Fabric, of which the following is a specification.

My invention relates to an apparatus for preparing inking-pads for use in printingpresses, and pertains especially to a means for applying a gummy or gelatinous elastic ink-transferring composition to removable pads for inking-rolls of presses of the cylinder type.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of the mold opened out and'the pump-cylinder removed.

Fig. 2 is a side elevation or partial section of,

the mold closed, showing method of applying the composition to the fabric. Fig. 3 is a rear end view of the mold. Fig. 4 is a perspective of the under side of a fragment of the toppresser-plate. Fig. 5.is a perspective view of a finished inking-pad. Figs. 6'

and 7 are perspective views, respectively, of the horizontal and longitudinal adjustable wall-strips. A represents a pad of canvas or like fabric of suitable size and generally rectangular in shape, to which it is designed to apply a suitable ink-transferring,composition, as indicated at a, Fig. 5. Tnis pad isprovided at the endswith suitable means, as the eyelets 2, whereby it may be held both in the molding machine when the composition is applied and subsequently upon the roller where the completed pad is used. B represents a suitable frame for the molding-machine, and 3 a flat-topped bed-plate pivoted at one-end, as shown at 4, to the frame, and adapted to be supported in hori- 'zontal position by suitable means, as the pivoted arm 5, on the bed-plate engaging the cross-bar 6 on the frame, as in Fig. 1, or to be supported in inclined position directly on the cross-bar 6, as shownin Fig. 2. Hinged to thebed-plate at one end andadjacent to pivots 4, as indicated at 7 is a hollow presserplate or cover 8, which is arranged to'be foldedover into a plane parallel with the surface of" the bed-plate and separated there- Specification of Letters Patent.

from only by a space equal to the thickness of the canvas and of the composition to be applied thereto. "The bed-plate is provided with the pins 9 at one end, over which the eyelets in one end of the canvas A are engaged. The other end of the bed-plate carfries a rotatable shaft or rod 10, having pins 11, to engage the eyelets in the other end of the canvas. This rod is fitted with a pawl and ratchet 12,' so that when the canvas is drawn taut it will be held in position. Having thus secured the canvas in position, the

these strips may be adjustable to and from each other to adapt them to the desired length of the body of composition. As here shown, one strip is permanently secured to the presser-plate, while the other has underturned ends engaging corresponding guides- 14 on the sides of the presser-plate. This ad-, justable strip is'locked in place by appropriate means, as the set-screw 15. The side of the adjustable strip 13 adjacent to the presser-plate istransversely channeled, asat 16, to permit air to escape when the compo sition is poured or forced in, as will be explained shortly. The adjacent edges of the strips 13 have notches 17 to receive the ends of the side strips 18, which are positioned according to the desired width of'the body of the composition and according to the desired location of the composition on the canvas.

' The thickness of the strips 13 18 is equal to the desired thickness of the composition body to be applied, and the joints of the strips with each other and with the presser-plate and the canvas when the presser-plate is closed down and clamped on the canvas are such as practically to furnish a tight inclosure except for the air-vents 16, above mentioned.

' The location and extent of the composition body is varied on different pads by moving the end strips 13 nearer to or farther from each other and by employing side strips 18 of required length and adjusting them toward or from each other and to one side or the other of the presser-plate.

The presser-plate is hollow to provide a chamber either for the receipt of a heating medium,,as steam,jor a cooling medium, as water, any well known' arrangement of next thing is to determine the space to be oc- ICS valved inlet and outlet pipes as', for instance, at 19 20being provided for the desired circulation of, the steam and water through the plate and for the discharge of water from said plate.

With the spacing-bars adjusted the hollow presser-plate is clamped down on the canvas by appropriate means, as the clamping-bars 22 and hand-wheel 23. The mold is then lowered into inclined position, as shown in,

Fig. 2, ready to receive the composition.

The end of the presser-plate has a socket communicating through a port 24 with the spaceinclosed by the strips 13 18. Acylinder 25 seats snug and is supported in the socket, but is readily removed therefrom and has an opening, controlled by a plug-valve 26, registrable with port 24:.

- The printing composition, which is a suitable gummy or gelatinous and elastic matter in a proper state of fluidity or semifluidity, is placed in the cylinder, the valve 26 opened, and by means of the plunger 27 the composition is forced down into the space inclosed by the strips 13 18 between presser-plate and canvas. Prior to this molding operation steam is passed through the presser-plate to heat the same to a high temperature to assist in maintaining the proper degree of fluidity of the composition. The latter by being made to flow uphill, due to the incline of the mold, reaches into all the corners of the latter and forms a solid casting free from airholes, since the air is allowed to pass out of the mold through the vents 16 and ahead of the encroaching fluid. As soon as the mold is filled the cook 26 is turned off and a stream of cold water run through the presser-plate to chill and set the composition. Subsequently the cylinder 25 may be detached, the presser-plate unclamped and opened, and the completed ad removed.

By having t e several parts of the pump separately removable it becomes easier to open up the mold, allows the cylinder to be maintained upright to prevent spilling of the composition, and renders cleaning of the 1 parts comparatively a simple matter.

It is possible that various modifications in my invention may be made without departing from the principle thereof, and I do not wish to be understood as limiting myself to the specific construction as herein shown and described.
